In summary: Starting with an initial investment of $26,000, you could potentially make $370,000 - $420,000.
In previous cycles, I often found myself struggling to find the answer to the question of "when to sell BTC and switch to Altcoins." BTC is meant to be held, not sold, and even more importantly, never sold for Altcoins. Simply hold onto BTC and when there's an Altcoin wave, use your BTC as collateral to borrow funds for Altcoin investments (ensuring borrowing remains under 30% of your capital). Now, with the increasing choices offered by the DeFi market compared to past cycles, this method proves quite effective for the strategy of using BTC as collateral to borrow USD for Altcoin investments.
From your expectation it seems that you are looking for the really high returns that are going to be life changing. Your starting investment it a good size to be split up into multiple coins and at least for me I would always prefer to reduce my overall risk instead of aiming for the highest possible returns. The next step for you is to take out loans to make even higher returns, which is a great move to the maximise returns. However, in case you are wrong and the market turns against you than you are going to lose your money twice. First in the market and the second time when you have to repay the loan. For me taking out loans for investing is too risky, I can't handle the stress with high volatility and will stick to only invest money that I already saved before. So, if you are really going for the highest possible returns than the Bitcoin market seems as not enough for you and it would be better to focus on Alt coins. In the alt coin market, the volatility is much higher which can lead to much higher price jumps. As long as you can handle bigger price swings then I would be allocating most of your money in the Alt coin market.
